Abstract

OBJECTIVE: To evaluate the change of ovarian reserve after unilateral laparoscopic ovarian cystectomy (LOC) in the early postoperative period between patients divided according to histologic diagnosis of cyst type. MATERIALS AND METHODS: Sixty-five patients who were undergoing unilateral LOC for benign ovarian disease were included in this study. All participants were divided into three groups according to histologic diagnosis: endometrioma (n=26), mature teratoma (n=24), and other benign cyst (n=15). Serum samples were collected preoperatively and 3-days postoperatively and assayed for antiMüllerian hormone (AMH) levels, and the changes between the two samples were analyzed. RESULTS: Preoperative AMH levels were not significantly different between the three groups. On postoperative Day 3 AMH levels of all three groups were significantly reduced compared with preoperative AMH levels. The rates of decline of AMH levels after LOC in patients with endometrioma (26.37±20.70%) and in those with teratoma (28.25±22.16%) were both significantly higher than those with other benign cyst (12.03±18.56%). No statistically significant differences were found in the rate of decline of AMH levels between patients with endometrioma and teratoma. Decline of AMH after LOC was not significantly correlated with age, body mass index, the size of cyst, or preoperative AMH levels. CONCLUSION: Our results suggest that ovarian reserve is reduced after unilateral LOC in the early postoperative period, and that the postoperative decline of AMH levels after LOC is similar between patients with endometrioma and those with mature teratoma.
